Branching codes for updates/revision before going live again

Branching codes for updates/revision before going live again

Hello Zoho Flow and Deluge team,

Currently, there is no way to create a branch of the existing code and having to copy existing code is creating many custom functions littering and making finding a custom function and especially finding the correct custom function difficult.

1. It would be nice to have code branching for existing codes in a custom function deployed to a live Zoho Flow. This would make modifying a live custom function code and adding functions/features easy. 
2. It would also be nice to be able to use previous data used in the previous custom function for testing the new code.
